Getting vaccinated for COVID-19 found to improve mental health
Mental distress before and after receiving the first dose. Note. PHQ-4 scores are standardized to have a mean of 0 and a standard deviation of 1. Residuals are taken from a linear regression of standardized PHQ-4 scores against wave dummy variables and an indicator for ever vaccinated. For the ever vaccinated, the residual is plotted against the number of days before or since receiving the first dose. Observations are grouped by wave. Vertical line denotes the date when a vaccination dose was first reported. Credit: Perez-Arce et al, 2021, PLOS ONE (CC-BY 4.0,

A team of researchers at the University of Southern California has found evidence suggesting that people who were vaccinated against COVID-19 experienced less stress afterward and saw resulting improvements in their mental health. The team has written a paper describing their year-long survey effort and what they learned from it and have posted it on the open-access site PLOS ONE.

The researchers were taking part in the Understanding America Study—a long-term project established at USC to track the impact of the in the U.S. on . The initial part of the project involved sending out more than 8,000 surveys to people across the country with questions geared toward gauging how the pandemic was impacting the mental health of people in general. Data from the surveys has shown that the majority of people queried have been experiencing some degree of anxiety and depression as a result of the pandemic. The team has continued to send surveys to the same people every two weeks as a way to measure changes in mental health as the pandemic has continued. In this lastest survey, respondents were asked about impacts on their mental after receiving a COVID-19 vaccination.

The researchers found that respondents in the study experienced a 15% decrease in the likelihood of feeling very depressed after being vaccinated and a 4% reduction in the likelihood of feeling just mildly depressed. The researchers also estimate that based on their data, it is likely that 1 million people have felt reductions in mental distress after being vaccinated.

The researchers further suggest their indicates that getting vaccinated against COVID-19 does more than just protect people from infection—it also greatly reduces the fear and anxiety people feel about their likelihood of being infected. They also suggest there might be more to the story, noting that they did not ask the respondents about reductions in stress in anxiety due to loved ones receiving vaccinations. They also note that the overall project is still ongoing—more surveys will be sent out to determine how people are feeling regarding the prospect of infection by variants and how they might feel after receiving booster shots.
